The Design And Implementation Of Group Enterprise Network Architecture And Security Deployment

Along with the rapid development of network technology and application, network architecture, IT basic operation system and information security are becoming the most important problems faced by enterprises that are building internal information networks. Basic networking is becoming the base and the key factor of building information structure; IT basic operation system provides an applicable platform for data and information exchange. Information security provides protection and control over data exchange for enterprises. The development level of the three combined not only represents the extent of basic information and information security that an enterprise has achieved, but also determines the direction for future development.First analyzes the status of network structure in the manufacture-based enterprises at home and abroad. Then it elaborates on the interrelationship among network,IT basic operation system and security system as well as the basic design concepts. Next, by implementing experimental projects, makes a detailed research and analysis on design and deployment of network architecture for enterprises, safety system and IT basic operation system, and also analyses the difficult problems and major failures incurred during implementation of those projects, and puts forward appropriate solutions and concept for the problems and failures. This thesis applies and involves some computer technologies like computer network, system and information security in designing network structure and safety deployment. This thesis concentrates on the design and realization of network architecture for enterprises and safety systems, and makes detailed analysis and explanation on a number of difficult problems, such as dual computers based on single group of networks, dual computers based on multi-group of series networks, networked QoS safeguard, network security zones, Network Access Security Control (NASC), and also provides the key configuration scripts for major problems and innovative concepts and key solutions of designing network and safety systems for the experimental equipments. At last, this thesis optimizes and integrates network, application and security system to finalize the plan for the design and overall deployment of network architecture for enterprises, IT basic operation system and information security system through implementing projects and presents analysis and research on practicability, reliability, expandability, controllability and performance bottleneck of the overall structure consisting of network, system and safety system.The final part of this thesis makes detailed test analysis and evaluation on network architecture for enterprises; system and safety structure, and optimizes and restores some tricky problems of network and system performance incurred in test results. The test analysis and results after readjustment show that the running and performance of the entire network structure have met the standards set for enterprises, and provide theories and practical examples for the design of future network architecture for enterprises. In the end, this thesis points out that intelligent network integration for enterprises and information security are key research directions for the design of future network architecture for enterprises and safety systems.
